γ-radiolysis of myo-inositol hexasulphate (free acid) in aqueous solution

Abstract

The effects of γ-radiation on aqueous solutions of myo-inositol hexasulphate in the free acid form have been studied. The results have been explained on the basis of radical initiated chain processes which lead to the observed high G-values for the ultimate inorganic product namely the sulphate ion and to low hydrogen peroxide yields. In addition, steady-state competition procedures and pulse radiolysis experiments show that the reaction between the OH and the substrate is slow.
